I spoke to a rep at the miami for the Konrads, 9k drive, they claim they could handle 1100 hp, but I think they only warrant 850hp. Suppose to be coming out with a shiftable drive soon too.
wahts the max on the xr drive and price?

An XR runs 7K-8K. An XR Sportmaster is 9K-10K. I blew up an XR in a few hours without beating on it. They are not meant for more than 600HP. You can baby them and get away with close to 800HP, but after that it's all over. I have an XR Sportmaster 1.5 up for sale ($6500) since it doesn’t do me any good with 1000+HP.

If i had the money, I guess the dry sumps 6's would have been the best choice if I was going to run 1100 hp - allowing for a trannie. "Hot BOat" this month had a nice article on history of drives and whats avaiable...though they didnt mention a few for some reason (hands werent greased I guess).

zt260, did they stand by the drive when it broke?

Mercury doesn’t stand behind anything drive related, unless it's with stock power.

Bmax warrantees their drive to 850HP.
For me he warrantees it to 1000HP due to the boat weight (4500Ibs)
